Tools like KiCad, Eagle, OrCAD the schematic capture entry "the drawing part" is kinda the least interesting part of the program. While there is an art to nicely designed schematics, especially analog/RF, most schematics in industry for densely populated boards are mostly just lots of blobs with net references - as an input into the next step of board design and footprint management. Ie its more CAM than CAD.
